The description of T. pectenis presented here first includes both live characters and morphometric data obtained from specimens impregnated using the wet silver nitrate and protargol methods. The other species were revealed by the dry silver nitrate method. Intensities of infestation and comparisons with related species and populations are provided for each of the four.展开更多
鉴定一种广西罗非鱼车轮虫,采用国际统一鉴定法及齿体定位法,根据齿体的形态和实际统计的齿体形态特征值与以往报道车轮虫比对。本种车轮虫在齿体形态特征值方面与Van As and Basson(1989,1992)报道的大型车轮虫(Trichodina magna Van A...鉴定一种广西罗非鱼车轮虫,采用国际统一鉴定法及齿体定位法,根据齿体的形态和实际统计的齿体形态特征值与以往报道车轮虫比对。本种车轮虫在齿体形态特征值方面与Van As and Basson(1989,1992)报道的大型车轮虫(Trichodina magna Van As and Basson,1989)统计特征值极为接近,即可确定本种车轮虫为大型车轮虫,此报道为国内首次关于大型车轮虫的报道,罗非鱼为其国内新寄主。展开更多

文摘在对重庆地区进行鱼类寄生虫学的调查过程中,从鲫鳃表获得3种隶属于车轮虫属Trichodina Ehrenberg,1830的外寄生车轮虫,其中含一新种,短棘车轮虫Trichodina brevicirra sp.nov,其典型的鉴别性特征为其短细的齿棘。另外两种车轮虫分别为沃玛车轮虫Trichodina ngoma Van As&Basson,1992与网状车轮虫Trichodina reticulata Hirschman&Partsch,1955;沃玛车轮虫为亚洲新记录种。文章对网状车轮虫的3种群进行了详尽的比较讨论研究,尽管该三种群间存在着细微的种群内差异,但网状车轮虫的典型特征则显而易见地存在于三种群间,即为附着盘中央具有8-16个球状或卵圆形的中央颗粒。
文摘鉴定一种广西罗非鱼车轮虫,采用国际统一鉴定法及齿体定位法,根据齿体的形态和实际统计的齿体形态特征值与以往报道车轮虫比对。本种车轮虫在齿体形态特征值方面与Van As and Basson(1989,1992)报道的大型车轮虫(Trichodina magna Van As and Basson,1989)统计特征值极为接近,即可确定本种车轮虫为大型车轮虫,此报道为国内首次关于大型车轮虫的报道,罗非鱼为其国内新寄主。
